object is-to provide a neat, durable" and inexpensive hingev provided with suitable for limitingthe opening-movement thereof. j '1' 1 vAs an enample of myjinvention I have v hereinshown a form of hinge which may be utilized in connection conventional type as a door stopjtolimitthe opening'of a door such, for instance, as the door of an automobile. readily understood by reference to the following description of that illustrative em bodiment shown in the accompanying drawings,.wherein:' U

door being in open position I Fig. '2 is a similar view with the door closed; 7

My invention is herein disclosed as. embodied in a device to limit the, opening movementof a doorso that it will not swing open too far. Forlexample, it will not swing through an angle of 180 and bang against the body of the vehicle on' which"v it.

Such aconstruction is obviously simple; and cheap and the construction to be describedpermitg the use of such a simple .form of "hinge connecotherwlse be considered tion which :might insufficiently staunch'gj-l Y a a To check movement of theleaves9 and 11 as they approachsdead center means which will oppose the straightening out ofthe toggle, such resilient-means being arranged to-ccome hinge sired maximum opening so that the door may 13 may conv'enientposition, which in the embodiment of the invention shown corresponds closely tothemaximum' o-pening J of. the" door, I: provide suitable resilient into actionz'during the latter part of theopeningmovement of the only shortly before it reaches its'de I I further provides. positive I it i in contact therewith and bear thereagainst shortly before the leaves assume the position shown in Fig. 1 and to yield resiliently on further movement of the leaves toward alignment. Thus in Fig. t I have illustrated the spring as just making contact with the back of the leaf 9 and in Fig. 5 the leaves 9 and 11 have been somewhat further traightened and the spring 11 has been tensioned indicated. J

It will be apparent that when the door is thrown open the leaves 9 and 11 will first open freely without any resistance until they come to the position of Fig. 4:- The spring 21 then coming into contact with the leaf is deflected by the further straightening movement, as shown in Fig. 5, cushioning this movement. To definitely limit the movement a suitable positive stop may be provided which is convenientlyformed by striking up. the projection 23 from leaf 9 on which projection the end of the spring 21 will seat in the manner shown in Fig. 6 preferably at a point slightly in advance of' the dead center position of the pivots. I have referred to this stop as'positive although obviously there may be a slight yielding of the spring but it is substantially a definite stop as compared with the action of the spring between the positions shown in Figs. 4. and 5. lVhen the parts have reached the positions of Figs. 1 and 6, obviously the opening movement of the door is definitely stopped. In the latter part of this straightening action, that is, the period between the positions of Figs. a .and'5, the movement has been cushioned and no sharp shock has been thrown upon the pintles and knuckles and while the positive stop is provided in a very convenient manner, it does not operate with a hammer blow as might be the case with ordinary shoulders on the hinge knuckles operating in'the manner of a so-called rule joint. Furthermore, in the preferred construction shown the hinge knuckles may, as already described, be formed as simple rolled knuckles most expeditiously and cheaply.

When the parts have reached the position shown in Fig. 6, the reaction of the spring may tend to return the leaves toward the position of Fig. 5 but there is no sharp rebounding movement which would tend to reclose the door as in the case of a hinge which operated against the spring throughout its opening movement. The leaves being definitely stopped before they reach dead center, there is no danger of the toggle breaking in the reverse direction so that instead of the links returning to their inconspicuous housed position between the hinge pillar and the hinge stile, as shown in Fig. 2, they would project into the interior of the vehicle when the door is closed. Furthermore, such re verse breaking of the toggle, might permit the door to rebound and the tendency of the links folding in the other direction would be to shut it prematurely.

I have described in detail the particular embodiment of my invention shown by way of example in the accompanying drawings. Obviously the invention is capable of other applications and of mechanical embodiments considerably different from that shown.

What I claim as new and desire to secure by Letters Patent 1 shall express in the fol-' lowing claims:

1. A stop hinge comprising a pair of leaves pivoted together and a flat spring secured to one leaf having an end extending over the pivot and presented to engage the other leaf only shortly before the'hinge reaches its desired maximum opening, said other leaf having a, projection on which the springseats when such maximum opening is attained. i

2. A stop hinge comprising a pair of leaves pivoted together, a stop for positively preventing relative opening movement of the leaves beyond a desired maximum and spring means effective only during the latter portion of the opening movement of the hinge for cushioning such movement and minimizing theblow on the stop.

3. A door stop comprising a air of hinged leaves provided with means or connecting them pivotally to the hinge pillar and hinge stile, said leaves adapted to fold between pillar and stile when the door is closed and extend substantially diagonally therebetween when it is open, means positively limiting the opening movement of the leaves and cooperating resilient means opposing their hinging during the lattermost part only of their opening movement:

In testimony whereof, I have signed my name to this specification.
